1 m Heat Source 1. A gas is in a container with a height of 1 m and an area of 1 m, with piston as the container top, weighing 200 N. The gas inside is initially at a temperature of 300 K. A heat source beneath the piston raises the temperature of the gas to 500K. a. What height will the piston rise to? b. How much weight (in N) should be added to the piston to return it to a height of 1 m? c. Can the pressure and volume both be reduced without any temperature change?
